Application iilcd June 4, 1887. Serial No. 240,307. (No model.)

.To all whom, it may concern,.- V

Be it known that I, EDWIN C. DERBY, a citizen of the United States, residing at Portland, in the county of Ionia and State of Michigan, have invented a new and useful Improvement in Land-Rollers, of which the following is a specication. v y

My invention relates to land-rollers; and it consists in the construction and combination o f the parts of the same, which will be more fully hereinafter described, and pointed out in the claims. Y

The object of. my invention is to provide a land-roller which is simple and effective in its construction and operation, strong and durable, easily handled, readily understood and operated, convenient and accessible, positive in its working and desired ultimate result, and cheaply manufactured. I attain this object by the construction of land-roller illustrated in the accompanying drawings, wherein like letters of reference indicate similar parts in the several views, and in which- Figure 1 is a perspective view of my improved land-roller. Fig. v2 is a top plan view of the same. Fig. 3 is a detail top plan view of one of the rollers.

A indicates a supporting-beam, to which a tongue, B, is secured by means of a bolt, b, passing therethrough and through the said beam A. 4A tie-brace,b,is secured to the top portion of the tongue B and projects over onto the beam A on each side ofthe said tongue. Under the tongue B one end of a brace, B', is secured, the other end of which projects downward and under the beam A, and is formed with an aperture, through which the bolt passes and secures it to the said beam. The forward end of the brace B is constructed With a loop, b2, to which the Whifiletree-lnk may be attached, thereby bringing the draft to bear upon a direct line to the center of the roller entire.

On each side of the beam Aand secured thereto are arranged two or more sots of hangers, C C,for two or more rollers,which are so arranged that when the rollers D D are arranged therein the rear roller will slightly overlap or project past the rear end of the forward roller and provide means thereby by which the whole surface may be traversed and rolled. These hangers C C are constructed of strong their vertical elevation.

strapiron,and are formed by doubling the'said strap-iron and then bending them so as to provide a vertical portion, c, and an inclined portion,c, as clearly shown in Fig. 1. The ends of the hangers are suitably secured to thebottom and sides of the beam A, and the ends of the axles play in the spaces between the branches of the hangers.

Suitable square faced metallic bearingblocks, d', are mounted in the lower portion of hangers O, which have apertures formed therethrough, andthrough which the ends of the axles D D pass and have free revolution. By this construction a steady vertical movement is allowed, and at the same time providing for the unobstructed revolution of the rollers D D. The limit of vertical movement of the blocks d', and consequently of the rollers D, is controlled and governed by adjustable metallic blocks @which are secured in the hanger by suitable removable means, and against which the blocks or movable bearings d strike in These blocks d2 may be adjusted to different positions in the hangers C, and thereby increase or decrease the vertical play and movement of the said rollers D. The rollers D will be constructed of material applicable for the purpose, and the size thereof and of the machine entire will be governed by the purpose and use for which the machine is to be made applicable.

By having the rollers D constructed movable at each side, as hereinbefore set forth, they are readily adjusted automatically to roll uneven surfaces, exerting at the same time the entire weight of the roller as a pressure upon said unequal surfaces, and greatly expediting and facilitating the leveling of said surface. The rolls will naturally resume their normal level position through the medium-of theforce of gravitation, as will be readily understood.

The simplicity, adjustability, utility, compactness, and practicability of my improved land-roller renders it of great value for many purposes, and, in view of its being comparatively inexpensive to manufacture,it is within the reach of every farmer.

It is obvious that many minor variations in the construction and arrangement of many of IOO fied and substituted for those shown and de- A scribed Without in the least departing from the nature and spirit of my invention.

Having thus described my invention, I claiml. In aland-roller, the combination of asupporting-beam, A, a tongne,.B, secured thereto by a bolt, I), and a tie-brace, b', and a Hat inetallie brace, B', secured to the under side of said tongue and extending under the beam A, and secured by the bolt b, and having a. loop, b2, in its forward portion for attach ment of the whiiietree, substantially as described.

2. In a land-roller, the combination of the beam A, having the tongue B, the hangers C, formed of strap-iron doubled on itself and p roviding the vertical portion o and the inclined portion c', the ends of the hangers being secured to the bottom andsides of the beam A, the rollers, the square-faced bearing-boxes d', mounted on the ends of the roller-axles 'and moving in the vertical portion of the hangers, and the square-faced stop-blocks d2, secured in the hangers and bearing against the boxes d', substantially as specied.

In testimony that I claim the foregoing as z5 my own I have hereto affixed my signaturein presence of two witnesses.

EDVIN C. DERBY.
